Up front, Pedrie Wannenburg has returned from a foot injury and will pack down at No 8 in place of Robbie Diack. Chris Henry will again captain the side from the blindside flank, with Willie Faloon remaining on the other side of the scrum. Dan Tuohy and Lewis Stevenson continue the partnership at lock. There are two changes in the front row with Paddy McAllister coming in at loosehead prop for Callum Black and Andi Kyriacou replacing Nigel Brady at hooker.
